Construction method of permeable weir for ecological landscape river

Abstract

The invention relates to an ecological landscape river channel weir body construction method. The ecological landscape river channel weir body construction method comprises the following steps that 01, a stable concrete foundation is arranged in a river channel, anti-sliding steps are arranged around the foundation, a row of annular grass planting precast blocks are laid close to the inner side ofeach of the steps, and round holes for greening and planting are formed in the middle positions of the precast blocks; 02, the middle of every two rows of annular grass planting precast blocks is filled and leveled with gravel with a diameter of 5-20 mm; 03, precast block paving and gravel filling are performed in sequence from bottom to top in a step mode, a layer of continuous geotextile is disposed between the gravel and the precast blocks, and the gravel is wrapped with the geotextile; the precast blocks are provided with anchor holes, and the anchor holes formed in the precast blocks arevertically aligned when overlapping, and the upper and lower layer precast blocks are connected through the anchor holes by glass fiber reinforced nylon rods; and 04, the round hole planting holes inthe middle of the precast blocks are filled with planting soil. The ecological landscape river channel permeable weir construction method increases filtration and landscape functions, has practicability and aesthetic property and protects the ecological environment.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a method for constructing an ecological landscape river channel weir body. Background technique [0002] In recent years, with the rapid development of my country's economy, the pace of urban construction has been accelerating, people are using urban rivers more and more frequently, and ecological requirements are getting higher and higher. Compared with natural rivers, urban rivers have more buildings, river landscapes are severely degraded, vegetation on both sides of the river is less, aquatic organisms are less, and water bodies lack vitality. The form of urban rivers is degraded, the rivers are narrow, generally shallow, straight, the water volume is small, the flow rate is slow, and the flow may even stop in dry seasons. These water conservancy characteristics determine that the environmental capacity of urban rivers is small and the ecosystem is fra...
